Angular (vs) REACT :


Technology

Angular

React

Created By

Google

Facebook

Technology Type

Component-Based Framework using Typescript

User Interface Library with a component-based architecture using JavaScript

Data Binding

2-way data binding

1-way data binding

Size

Quite large & since it needs to be shipped to the client side, it increases the initial load time

Quite small in size, especially when compared with Angular

Learning Curve

Quite Sleep, given the number of features & options you have in angular

Its easy to pick up and learn

Simplicity

Quite complex

Fairly simple but takes some time to set up a project and configure everything
         

Basic Architecture of Angular :            


   

What is a MODULE ?

✓ Module is nothing but JavaScript or typescript code.

✓ which is going to have variables, functions, class further we import and exports.

✓ Module is  .jS or .ts Files.





✓ Module in Angular refers to a place where you can Group the Components, Directives, Pipes & Services which are related to the application.

✓ Every Angular application have atleast One Module, which is called RouteModule and it's naming convection is AppModule.

✓ It reside inside the App.Module.ts file.

What is a COMPONENT ?

✓ Major part of the Development is Done in the Components.

✓ Components Control the portion of the View in the Browser.

✓ Components are basically Classes that interact with the .html file of the Component, which gets displayed on the Browser.

✓ Every Angular application has atleast One component which is Root Component & by convention it is AppComponent.









Summarize the Architecture :

✓ Angular Application : One or More Modules

✓ Module : Html Template + Class to control the logic to the particular View.

✓ Service : Business Logic.

✓ Finally, Modules interact with each other and render view in the Browser.
